TDS érzékelő modul, analóg jel, oldott szilárd anyagok, vízminőség-érzékelő, alkalmas 51/stm32-re
TDS sensor module, analog signal, dissolved solids, water quality detection, suitable for 51/stm32
Product Introduction
TDS (Total Dissolved Solids), the total amount of dissolved solids, indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. Generally speaking, the higher the TDS value, the more dissolved substances contained in the water, and the less clean the water will be. Although TDS cannot effectively reflect the water quality under certain circumstances, as a parameter that can be quickly detected, TDS can still be used as an effective water quality reflecting parameter as a reference.
The commonly used TDS testing equipment is a TDS pen. Although it is cheap and easy to use, it cannot transmit data to the control system for long-term online monitoring and water quality analysis. Using special instruments, although it can transmit data, the accuracy is also high, and the price is very expensive. To this end, we specially introduced this TDS sensor module. The module is plug-and-play, simple and convenient to use. The excitation source for measurement uses AC signals, which can effectively prevent head polarization, extend the life of the probe, and increase the stability of the output signal. The TD probe is a waterproof probe that can be immersed in water for long-term measurement. The product can be applied to water quality testing in the fields of domestic water, hydroponics, etc. With this sensor, you can easily DIY a set of TDS detector to easily detect the cleanliness of the water and check your water quality.
